Clutch Problem

[79XS11F]

Can you put this engine through all the gears with it not running. You should be able to find every gear with the bike on main stand, the clutch being pulled for each change and the shifter being worked while Turing the rear wheel by hand.

Yes,
I can go through every gear with it not running easily.

I took it apart again and found one frition plate was very slightly warped. Would that even make a difference, it was a very small amount of play. All washers were in the correct locations and no burrs were found.

Thanks Again

OK ... is there any side to side or up and down play on the clutch shaft? Is there back and forth play on that shaft?
Are the fiber and steel plates stacked in the correct order from start to finish?

Hey Chevy,

How thick are your frictions? Spec is 3.00 mm, out of spec is only 2.80 mm. I have heard of folks who had put in Barnett clutches and they had trouble disengaging them. You don't know what brand the frictions are probably? You can get Generic ones from PNM(www.partsnmore.com) for $5.00 ea.! Don't know whether you would want to replace them all, or just the warped one??

Also, have you checked the springs lengths? IF you'll go to the MAIN FORUM PAGE, and scroll down to the Mods, you should find a tip on the Extra Steel plate tip..not saying you want to do that, but there are plenty of photos and info on the springs, as well as cautionary info about the star plate R&R. You've already done it, but a bit more knowledge can't hurt!?

clutch not disengaging

"I put everything back the way I took it apart" Do you have an exploded diagram (service manual) of the clutch assembly? Mabye the guy before you assembled it incorrectly? JAT

79XS11SF- There is Not any Side to side Up down Are In out movement of the clutch shaft.
I put a Fiber on the bottom then back in fourth 'till a fiber on top.

TopCat- I will measure my frictons Tommorrow. NO i dont know what brand they are.
The springs are right at the specs that it said in the Tech article that you are talking about.

I noticed that the sprins look like they were Painted Blue at one time, MAYBE they are aftermarket performance Springs. I am not sure.

bikerphil-No I dont have a Manual. I am using a Parts diagram as my source.


Thanks Again.

Acording to that Diagram I have the parts in the correct locations.

[ChevyBoy]

Ok,

Anything else I should check before I put it together again...

Dont know what else to try!

Thanks for all the ideas.

Does anyone have any more ideas on my Clutch Problem?

How can I tell if they are Barnnet Clutches?

Is there Any other Company that sells Good Original clutches?

Thanks Again

clutch friction plates

I use the ones from Partsnmore.net. They are inexpensive and i've never had any problems with them. I have at least 45K on a set right now and they are still fine. Did you check the clutch shaft bearing(s) to see if there is any slop in them?

[trbig]

It sort of sounded like you only checked for burrs on the plates... this is where you need to be checking.




All this just doesn't sound like a clutch issue to me. Seems more like bent shift forks making everything out of alignment and holding the dogs of a gear too deep to let the shift cam/drum disengage it from the other gear's slots. Then while it's in that gear, your trying to put it in another one...

A clutch is going to have issues of engage/ disengage... not make horrible sounds/ shudders out of the tranny while in gear.

Just my guess that someone may have had 1st/2nd gear issues then held the shifter down to keep it in gear. But... I have been wrong before.

I might get the the clutch plates that yall are talking about from PartsNMore.

The tranny makes a Noise when you are going fromn Neatrul to Another Gear. Makes a Grinding Noise like the Clutch is NOT disengaged.

Then when you get it into gear Everything is Perfect UNTIL you let out the clutch Handle, Then it shakes and Jerks.

Thanks for The picture I am going to take Every little Burr that I can find Off.

Thanks Again

I've got barnnet frictions in one XS (pretty sure they be red).
No problems with plates, but did crack the clutch basket in that bike once. Only time it made weird noise or didn't feel right was when letting the clutch out. Once out if you didn't get radical with the throttle it seemed to operate normally. All be fine once I replaced the basket.

I DE-Burred all the edges of the basket and the clutch housing, And lightly sanded the Corners so they wouldnt grab,.
I put the bike all back together. And It did the excat same thing.

I realized that the Shudder and Jerk were caused by the engine wanting to Dye Out because of the load And not Revving the engine. When I just brought the throttle Off Idle the Shudders and Jerks went AWAY and it ran perfectly.

Still grinds the gears when you try to put it into Gear.

Thanks Again.
